5. Pharmacological properties
5.1 Pharmacodynamic properties
A12A X-Calcium, combinations with other drugs.Crampex Tablets contain three active ingredients, calcium gluconate, nicotinic acid and Cholecalciferol. The inclusion of calcium gluconate is intended to correct any sub-clinical deficiency of calcium that may exist. The vitamin D status of the elderly may border on the deficient and as their vitamin D intake is often inadequate, Cholecalciferol is contained in the formulation to ensure satisfactory calcium absorption. As it is possible that a poor peripheral circulation may be an aggravating factor in the induction of cramps, the formulation includes the vasodilator, nicotinic acid.
